Hi DPDK expert,
I am Nokia engineer. We are upgrading 6wind from 6wind 4.13->4.17, with DPDK upgrading from 16.04->17.05. We use AVP PMD driver.
>From the performance test result, the CPU load of RX core increase from 72% to 94% under same pps. The bitrate decreased from 9800M to 9000M, limitation is also in RX core.
The difference is only 6wind software and DPDK code.
Do you have some test result for DPDK AVP PMD driver for release 16.04 and 17.05?
Do you have some suggestion to increase the AVP PMD driver performance? Is the later version have any improvement for AVP?

Waiting for your response.

Thank you!
Wang Qihua
